Abstract: A CONTAINER FOR LIQUIDS Abstract of the Invention An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material.  The carton preferably includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carton may be consumed by a user.  The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carton blank upon a rotating heat sealing and alignment drum.  A conveyor for collating a plural number of the carton blanks about a forming mandrel is also provided, and is positioned transversely to the remainder of the apparatus thereby significantly reducing the overall size of the apparatus.  An ultrasonic welder bonds the side seams and end closure panels of the container upon a rotating crossbar mandrel which eliminates any misalignment during the sealing process.  A substantially rigid conveyor transport carries a plurality of the carton blanks through pre-form, filler, and end closure work stations, and includes plural anvils for the ultrasonic welding process.  An ejector mechanism is additionally provided which ejects the filled carton blanks from the rigid conveyor along a dual direction path, thereby eliminating the possibility of creasing or puncturing the filled and sealed container.  The apparatus of the present invention additionally accommodates the production of differing size containers with only minor adjustments.

Abstract: Abstract of the Disclosure A device for detecting a key switch operation capable of detecting an operating state of a plurality of key switches which are commonly connected with respect to each row line (block line) at one terminal thereof and commonly connected with respect to each column line at the other terminal thereof, thereby constituting a switch matrix.  If a signal is provided on all column lines, the signal is transmitted to a block line through a key switch which is in operation and thereby a block including the key switch in operation is detected.  A signal is then supplied from the detected block line to a column line only through the key switch in operation in the detected block.  The position of the key switch in operation is known by detecting the column line on which the signal arrives.          According to an embodiment of the invention, capacitance elements are provided both on the block lines and on the column lines for effecting delivery of the signal by charging and discharging of these capacitance elements.  There is also disclosed a construction in which detected blocks are once stored in a memory and positions of key switches in operation in the detected blocks are detected and stored block by block. The stored blocks and key switch positions are codified to produce key codes identifying the key switches in operation.

Abstract: ABSTRACT OF THE DISCLOSURE     Refractory parts or articles, even of very large dimensions, and exhibiting improved resistance to thermal shock are made from a starting mater-ial of carbon particles mixed with silicon particles in a predetermined ratio which is suspended in a solution of a binder, after which the suspension is squirted into a precipitating liquid to coat the particles with the binder.     The solids are then separated and dried, molded under slight pressure, and coked (at 800 - 1,000°C), and then rapidly raised in temperature (to 1,400 -1,600°C) for formation of silicon carbide throughout the article.  It is useful to add powdered silicon carbide and mix it in before the coking step and, also, to hold the heated body at a temperature somewhat below 1,400°C long enough to remove temperature gradients within it, followed by rapid heating up to a carbide-forming temperature.  The porous bodies thus formed can be heated to reduce porosity after the coking step by impregnation with a suspension of silicon powder in a resin, after which the body is again coked, or impregnation may be carried out on the completely fired body, with a liquid resin or a molten metal, after evacuation of the porous body and the application of pres-sure to the impregnating fluid.

Abstract: ABSTRACT      A step-and-repeat alignment and exposure system is provided with an adjustable holder for holding a main reticle, a main optical unit including a projection lens for produc-ing an image of the main reticle at an image plane, a stage movable along coordinate axes adjacent to the image plane, and a holder rotatably mounted on the stage for holding a semiconductive wafer to be aligned with respect to the image of the main reticle.  The system is further provided with an adjustable holder for holding an auxiliary reticle, a single channel auxiliary optical unit including a main objective lens for producing an image of the auxiliary reticle at the image plane, and a reference mark disposed on the stage and aligned with respect to the coordinate axes.  The stage may be con-trolled for positioning the reference mark directly beneath either the projection lens or the main objective lens of the single channel auxiliary optical unit so that the images of both the main reticle and the auxiliary reticle may be aligned with respect to the reference mark and, hence, with respect to the coordinate axes, and so that the relative spacing between these images may be determined and checked from time to time.          This permits the main optical unit and the auxiliary optical unit to be employed interchangeably in globally and precision region-by-region aligning the semiconductive wafer with respect to the coordinate axes prior to employing the projection lens in the photometric step-and-repeat printing of the image of the main reticle at each of an array of different regions on the semiconductive wafer.  The system also includes a light source unit for selectively frontally illuminating the entire field of view of the main objective lens of the single channel auxiliary optical unit with white light not passing through the auxiliary reticle.

Abstract: ABSTRACT OF THE DISCLOSURE    A variable speed motor controller for an AC motor, said controller including a DC to AC converter for providing adjustable frequency AC signals to vary the speed of said motor, and a sensing device and energy saving control for detecting the magnitude of the current signal being supplied to the motor and ad-justing the AC voltage to the motor depending upon the magnitude of the current signal.  The smaller the motor current being sensed, the smaller the voltage applied to the motor, thereby effecting a saving of energy.          Energy is saved using this controller because when the lesser motor current indicates that it is driving less than full load, the input voltage applied to the motor is reduced thereby effecting a power saving.

Abstract: POSTAGE VALUE CALCULATOR WITH EXPANDED MEMORY VERSATILITY                 ABSTRACT OF THE DISCLOSURE     A postage value calculator system includes a processor which receives article weight, destination, class and carrier type information for transportation of the article.  The processor accesses a directory which vectors to memory lo-cations to retrieve rate data for generation of a postage value.          The system includes an address counter which is incremented to access successive memory address locations.  All system memories include uniformly spaced storage locations which are reserved for addressing purposes only.  Each time the address counter is incremented, a check is made to determine if the location reached is reserved for addressing data.  If the location is not reserved for addressing data, the stored postal information is used for the postage computation routine.          When the incremented address is that of the addressing data, the word stored in the memory is loaded into the upper byte of the address counter, the lower order byte is set to zero, and the program continues at the new address.  Conservation of memory space and increased memory versatility is thereby obtained.
